Investment Objective/Strategy -First Trust Global Wind Energy ETF is an exchange-traded fund. The investment objective of the Fund is to seek investment results that correspond generally to the price and yield, before the Fund's fees and expenses, of an equity index called the ISE Clean Edge Global Wind Energy Index.

There can be no assurance that the Fund's investment objectives will be achieved.

This exchange-traded fund seeks investment results that correspond generally to the price and yield
(before the Fund's fees and expenses)
of the ISE Clean Edge Global Wind Energy Index. The index is constructed as follows:

Companies in the index universe that are identified as providing goods and services exclusively to the wind energy industry are given an aggregate weight of 66.67% of the index.Those companies determined to be significant participants in the wind energy industry despite not being exclusive to
such industry are given an aggregate weight of 33.33% of the index.This weighting is done to ensure that companies that are exclusive to the wind energy industry, which generally have smaller market capitalizations relative to their multi-industry counterparts, are adequately represented in the index.

The index uses a modified market capitalization weighted methodology for each group of companies. The methodology organizes the companies into quintiles based upon their market capitalization. The quintiles containing larger market capitalization companies receive a higher weight than those quintiles
containing small market capitalization companies.The resulting weight distribution prevents a few large companies from dominating the index while allowing smaller companies to adequately influence index performance.The companies are equally-weighted within each quintile.

The component security must be actively engaged in some aspect of the wind energy industry such as the development or management of a wind farm, the production or distribution of electricity generated by wind power, involvement in the design, manufacture or distribution of machinery or materials designed specifically for the wind energy industry.

Each component security must have a market capitalization of at least $100 million and meet certain investability requirements.

The index is reconstituted and rebalanced semi-annually.

of excess reward per unit of volatility. Correlation is a measure of the similarity of performance.

*Performance data quoted represents past performance. Past performance is not a guarantee of future
results and current performance may be higher or lower than performance quoted. Investment returns
and principal value will fluctuate and shares when sold or redeemed, may be worth more or less than
their original cost.

After Tax Held returns represent return after taxes on distributions. Assumes shares have not been sold.
After Tax Sold returns represent the return after taxes on distributions and the sale of fund shares. Returns
do not represent the returns you would receive if you traded shares at other times. Market Price returns are
based on the midpoint of the bid/ask spread on the stock exchange on which shares of the fund are listed for
trading as of the time that the fund’s NAV is calculated. Returns are average annualized total returns, except
those for periods of less than one year, which are cumulative. The fund's performance reflects fee waivers
and expense reimbursements, absent which performance would have been lower.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and
do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax
situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold
their fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

**Performance information for the ISE Clean Edge Global Wind Energy Index is for illustrative purposes only and does not represent actual fund performance.

The gross expense ratio for this fund is 0.71%.Expenses are capped contractually at 0.60% per year, at least until January 31, 2019.

Fund shares are purchased and sold on an exchange at their share price rather than net asset value (NAV), which may cause the shares to trade at a price greater than NAV (premium) or less than NAV (discount).

4

5

The unsubsidized 30-day SEC yield is calculated the same as the 30-day SEC yield, however it excludes contractual fee waivers and expense reimbursements.

ETF Characteristics

The fund lists and principally trades its shares on the NYSE Arca, Inc.

The fund's return may not match the return of the ISE Clean Edge Global Wind Energy Index. Securities held by the fund will generally not be bought or sold in response to market fluctuations.

Investors buying or selling fund shares on the secondary market may incur customary brokerage commissions.
Market prices may differ to some degree from the net asset value of the shares. Investors who sell fund shares may receive less than the share's net
asset value. Shares may be sold throughout the day on the exchange through any brokerage account. However, unlike mutual funds, shares may only be
redeemed directly from the fund by authorized participants, in very large creation/redemption units. If the fund's authorized participants are unable
to proceed with creation/redemption orders and no other authorized participant is able to step forward to create or redeem, fund shares may trade at
a discount to the fund's net asset value and possibly face delisting.

Risk Considerations

The fund's shares will change in value, and you could lose money by investing in the fund. One of the principal risks of investing in the fund is market risk. Market risk is the risk that a particular stock owned by the fund, fund shares or stocks in general may fall in value. There can be no assurance that the fund's investment objective will be achieved.

The fund may invest in small capitalization and mid capitalization companies. Such companies may experience greater price volatility than larger, more established companies.

The fund may invest in securities issued by companies concentrated in a particular country which involves additional risks including limited diversification.

An investment in a fund containing securities of non-U.S. issuers is subject to additional risks, including currency fluctuations, political risks, withholding, the lack of adequate financial information, and exchange control restrictions impacting non-U.S. issuers. The fund may invest in depositary receipts which may be less liquid than the underlying shares in their primary trading market.

The fund contains the securities of companies in the wind energy, utility and industrial sectors, among others. Wind energy companies can be significantly affected by obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants and general economic conditions. This can be significantly affected by fluctuations in energy prices and supply and demand of alternative energy fuels, energy conservation, and government regulations.

Industrials companies are subject to certain risks, including include the general state of the economy, intense competition, consolidation, domestic and international politics, excess capacity and consumer demand and spending trends. They may also be significantly affected by overall capital spending levels, economic cycles, technical obsolescence, delays in modernization, labor relations, and government regulations.

Utilities companies are subject to imposition of rate caps, increased competition, difficulty in obtaining an adequate return on invested capital or in financing large construction projects, limitations on operations and increased costs attributable to environmental considerations and the capital market's ability to absorb utility debt. Utilities companies may also be affected by taxes, government regulation, international politics, price and supply fluctuations, volatile interest rates and energy conservation.

Changes in currency exchange rates and the relative value of non-US currencies may affect the value of a fund's investments and the value of a fund's shares.

The fund is classified as "non-diversified" and may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly concentrated in certain issuers.

First Trust Advisors L.P. is the adviser to the fund. First Trust Advisors L.P. is an affiliate of First Trust Portfolios L.P., the fund's distributor.

sold or promoted by the International Securities Exchange (ISE).
